The webbings 5 and 5, the webbing 6 having one end fixed to the lower portion of the bracket, the seat belt retractor 7 for winding the other end of the webbing 6 to pull the bracket 4 downward, and the like.

The other ends of the webbings 5 and 5 are formed in a loop shape, and the engaging portions 4 formed on the left and right of the upper portion of the bracket 4
a and 4a are detachably hung and connected.

Further, in the seat belt device 3, a plurality of sets of holes 8 through which the webbings 5 and 5 are inserted in the seat back 2,
8 is formed in three stages.

[0006] One end of the webbing 5, 5 is passed through the hole 8, 8 in one of the steps of the seat back 2,
On the front side of the.

The webbing 5, 5 can be adjusted according to the sitting height of the child by passing through the hole 8, 8 of any step.

[0008]

By the way, in the seat structure described above, when it is desired to pass the webbings 5 and 5 through the holes 8 and 8 different from the holes 8 and 8 that are currently inserted, first, the webbings 5 and 5 are used. To the other end of the bracket 4 of the bracket 4 4a, 4a
Then, the seat 8 is pulled out to the front side of the seat back 2 from the holes 8 which are currently inserted.

Next, the other ends of the webbings 5 and 5 are respectively passed through the holes 8 and 8 of different steps, and then hooked again to the locking portions 4a and 4a of the bracket 4 on the back side of the seat back 2.

As described above, in the conventional seat structure, when changing the steps of the holes 8 and 8 through which the webbings 5 and 5 are passed, it is necessary to separate the webbing 5 and 5 from the bracket 4. The change work of No. 8 was very complicated and troublesome.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a vehicle seat structure capable of easily and quickly changing the step of the hole through which the webbing of the seat belt device is passed. And

In the present invention, in order to achieve the above object,
In a vehicle seat structure in which a child seat portion is built in a seat back, and a pair of webbing holes of a seat belt device used for the child seat portion is provided in the seat back, at least the hole is provided in the seat belt. Formed on the seat back with the width of the pad of the device,
It is configured such that the lower central portion of the hole is raised.
